Flat foot shifting

The purpose of this feature is to allow you to hold the throttle fully open while shifting gears.

The FFS limiter is enabled when the vehicle speed is above the LC speed threshold and the clutch pedal is depressed.

What benefits can you expect from using FFS?

Reduced stress on the transmission when used properly

Boost will not drop between shifts as the throttle remains wide open

Launch control

The purpose of this feature is to allow you to hold your foot planted to the throttle while stationary and forcing an RPM delta (offset to real rev limit) that allows the car to hold a user desired rev limit and launch with as much less wheelspin as possible when releasing the clutch.
